L PARKER ETAL COVER AND LOCK FOR TOILET FLUSH TANKS Fi1ed May 10. 1948Paented Nov. 6, 1951 -1 ul' invention relates to a cover and 10ck fortoilet ush tanks, and the 0bects 0f our;inven" l...ion are:

- First, to provide a cove1 and 10ck '0f this cl;sS vvhich eeetivelyprevents the inadvertent breakage Oftoilet iuSh tank covers of' bonventiona1 des g1 Whichn1ay be easily displaeed fro!n the c0nventi0nl tank,pernittin san1eto fa11 and crack;

Second, to provide a cover and lock of this class which is readilyadapted for use in connection with toilet 1uSh tanks with only Slightchanges;

'Il1il'd, to provide a cover and lock 0f this class which is very snpleand eSy to engage or disengage when placing or ren10ving covers oftoilet uSh tankS;

Fourth, t0 provide a cover and lock fol' toilet iiush tanks Which doesnot obstruct the 0per ating mechanism within the tank; and

Fifth, to provide a' cover and lock f0l' t0ilet flush tanks of thisclass vvhich is very sirnple and econonlica1 0f construction, efcient inop eration, and which will not readily deteriorate or get out of orderwith these and other objects in view, as will appear hereinafter, ou1invention consists of certain novel features of construction,c0!nbination and arrangenlent of parts and portions as will beheeinafter described in detail and particularly Set forth in theappended cla'i!ns, ref erence being had to the accon panying drav7 ingsand to the characters of reference thereon, fornling a' part of thisapplicati0n, in which:

Fig. 1 iS a perspective view of our cover and lock for t0ilet uSh tanks,Shown on a iiush tank }...'ig. 2 iS an enlarged frag!1entary sec tionalview, taken fro!n the line 2-2 of ig. 1- Fig. -3 is a reduced sectionalview taken from the line 3-3 0f Fig. 2. 1'ig. is a' 1'educed sectiona1vievv taken fron1 the line Of 'ig. 2

sinlilar characters of reference refer to sinilar parts and portionsthroughout the several views of the drawing 'he tank I, cover 2, latch3, latch release 4, and pad 5 constitute the principal parts andportions of our cover and ck for toilet flush tanks.

The tank l is a substantialy conventiona1 rectangular tank, providedvvith an invvardly ex tending 1ange piece on one end there0f adjacentthe upper open Side of the tank, as shown in Fig. 2 0f the drawings. 2is substantia11y rectangular having overlapping the drawingS; "'Integra1with the cover 2- is 'ai projection 25, ete ding d0wnward1y on an in61ine toward' the ange of the tank secured on the end of this projection2b is the pd 5, Which is nlade of any Suitable resilient or 1iexiblematerial desired This pad 5 engages the flange |(z at its il1wardlyextending smooth, rounded end. and the resilient character of this pad 5Inaintains Slight tension on the cover 2, h01ding the sanledovvnvv9ardly over the upper end of the tank In the 0pposite end of thecover 2 fronl the projection 2b we have provided a slot 2C, in vvhichthe angularly extending end 3c of the Spring latch 3 is engaged. Thisspring latch 3 extends at SubSta tially right angles to the plane of thecover 2 and is provided with an offset latch portion 3Z engaging aninvvardly extending projection le on the inner end wall of the tank I1elatch 3 is provided with an arnl portion 3C extending beyond the osetlatch portion 3h engageable by the reciprocally operated latch release4, vvhich is slidably Inounted on 9 horizontal bore por tion l(z in oneend wall of the tank as shown best in 'ig' 2 0f the drawingS ''heoperation of our cover and 10ck for toilet flush tanks is substantiallyas follows:

vvhen the cover 2 is secured on the tank l aS Shovvn in Fig. 2 0f thedrawings, the projection 2b which iS rigid, Supports the flexible pad 5in fir!nly engaged relationship with the in vvardly extending flange |(Znear the upper end 0f the tank l. 'he resi1ient characte1 of the latch 3tends to force the saIne against the inner end wall of the tank intosecure engagement with the inwardly projecting latch portion lc integralwith the inner side of the end Wall of the tank I, as shown in Fig 2 0fthe dravvings I'he cover 2 is thus prevented fron1 inadvertent re!novalfroln the tank and in the event it is desired to ren10ve the cover 2frotn the tank l, the latch release 4 iS pressed inwardly, which engagesthe ann portion 3C of the latch Inelnber 3, thus disengaging the off-Set portion 3b from the latch portion lc of the tank pern1itting theflanges 2C 0f the cover 2 to be engaged for vertically nloving the latchend of the cover 2 upvvardly to aJ Slightly inclined position, S0 thatthe pad Inay be resiliently IIaving thus described ou1` invention, W;1avve clailn as llevv and desire t0 Secure by Letters curved downwardl onits u r edge nd t rconnected to said cover near its opposite endextending downwardly into said tank, a rojection having an u er beveledportion and a' 10Wer shoulder extendj11g from the innel' side wall ofSaid tank, Said laitch having a lower off- Set shoulder portion and abeveled upper portion engageable with said projection, said tank havingvan opening extending through the Side wall there0f, and a re1easemember Slidably mounted in Said opening, adapted to engage and deect Sidlatch 1T1en1ber for disengaging the sanle fron said i lwardly projectingportion of said lt1inating in a' rounded or curved extreniy of LE0PARKER.
